Transactions on Emerging Telecommunications Technologies, 2022
AbstractChannel estimation (CE) and spectral efficiency (SE) are two processes that have a major influence on system performance, especially in a more practical channel scenario with spatially correlated Rayleigh fading. During this work, we address the uplink phase CE process and the SE for spatially correlated Rayleigh fading in a cell‐free (CF ...

2008 IEEE Antennas and Propagation Society International Symposium, 2008
Under the various conditions such as the positional changes of AP and UT, aspect ratio of the room size, and radiation pattern of UT, we evaluated the channel capacity which depends on AP antenna configuration in indoor MIMO systems by the ray-tracing simulation.

Evaluation of the antennas performance for three-element MIMO access points in a two-storey house
2015 Loughborough Antennas & Propagation Conference (LAPC), 2015In this paper, the antennas performances for the 5.2 GHz 802.11n network are compared by three different access points with 3 antenna configurations based on the simulated throughput derived from measurements in a two-storey house. The aim here is to outline a methodology for access point performance taking account client orientation, MIMO data streams
